Why do I need a Building Permit?

The California Building Code requires a Building Permit for new construction, remodeling and tenant improvements for both commercial and residential projects; a mechanical permits for installation or replacement of mechanical equipment, such as furnaces, air conditioning units, hoods, boilers, etc.; an electrical permits for electrical equipment and electrical installations associated with other equipment, such as:

  • Electrical panels and services
  • Electrical wiring
  • Lighting fixtures
  • Outlets
  • Signs

A plumbing permits for installation or replacement of plumbing fixtures such as sewer, water and gas lines, water heaters, sinks, water closets, etc.

If you are found performing construction work without the benefit of a building permit, a Building Inspector may stop the work in progress. Work cannot continue until a proper permit has been obtained. In these cases, permit fees are doubled. Work done without the benefit of inspections can pose a health and safety hazard and potentially make it harder to sell your home.
